66 QXS G2 Hardware Installation and Maintenance Guide
NOTE: When moving FDE-capable drive modules for a disk group, stop I/O to any volumes in the
disk group before removing the drive modules.
Follow the procedures in “Module removal and replacement” for replacing drive modules relative to
the chassis type (2U or 5U). Import the keys for the drives so that the drive content becomes
available.
Federal Information Processing Standards (FIPS)
FIPS are U.S. government computer security standards that specify requirements for cryptography
modules. FIPS is a widely recognized and demanded cert when it comes to government agencies and
industry’s subject to strict security compliance. FIPS certification is available on self-encrypting drives
(SEDs).
Connecting RAID Chassis and Expansion Chassis
Use this section to connect the RAID chassis to the expansion chassis. Connecting/cabling suggestions
are provided. The customer can select the applicable connecting/cabling best suited for their
installation.
NOTE: Reverse cabling/straight-through cabling for the RAID chassis and expansion is provided.
Reverse cabling is suggested because it provides redundancy (alternate path to access chassis).
Table 9 provides the RAID chassis system, drive form factor per chassis, and the number of expansion
chassis supported in a RAID chassis and expansion chassis combination.
The chassis support both straight-through and reverse SAS cabling. Reverse cabling allows any drive
chassis to fail—or be removed—while maintaining access to other chassis. Fault tolerance and
